' Application filed )ctober 17, 1901. Serial No. 79,031. (No model.)

To all whom, it mag concern:

Be it known that I, JOHN FOX, a citizen of the United States, residing tat 234 East Thirty-third street, New York, county of New York, State ofNew York, have invented certain new and useful Improvements inCarbonators for Beverages, fully described and represented in thefollowing specification and the accompanying drawings, forming apart ofthe same. 1

The object of this invention is to furnish an apparatus for makingcarbonated or aerated liquids and which shall be cheap in itsconstruction and eflicient in its operation.

. The apparatus may be used to impregnate water and other liquids withcarbonic-acid gas under pressure and is especially adapted to permitthecleaning of the shell and the perforated disks whichserve-todisseminate the gas through the water.

The invention will be understood by reference to the annexed drawings,in which- Figure'l is a vertical section of the apparatus on line 1 1 inFig.2. Fig. 2 is a plan of the bottom upon a reduced scale. Fig- 3 is aperspective view of one of theperforated disks with flanged edge, andFig. 4 is a similar view of one of the disks with ahoop fitted insidethe flange. Figs; 3 and 4 show the disk inverted.

a. designates the shell or casing of the vessel which contains the gasand water chamber and which is shown connectedwith the bottom b by meansof a locking-rin'g'c, secured to the bottom of the shell, and removableThe bottom b is dished, and a perforated grating leis inserted withinthe casin g, resting upon the bottom and forming a chamber Z between thegrating and bottom, which cham not connected with the chamber Z; but agaspipe mis connected through the grating with the nozzle f and isextended horizontally just above the surface of the grating and providedupon its lower side with holes which directl jets of gas downwardly uponand through the'grating. The end of the pipe is closed, so that the gasis delivered only from the jet-holes. The pipe m is formed with a socketwhich screws upon the nozzle f, so that it can be readily removed whenit is desired to separate the grating from the bottom.

A series of eleven perforated screens or disks 'IL is shown fittedhorizontally within the'casingandeach formed upon the edge with adownwardly-turned flange n, which operates to space the disks apartandto support the bottom one upon the grating is. The disks areconnected centrally by a bolt q, having nuts at its opposite ends, theone at the lower end lying in the space between the bottom disk and thegrating is. Bushings s are threaded upon the bolt between the disks tospace them apart at the center and sustain the clamping pressure of thenuts. The disks are also supported and spaced apart by a spaced seriesof studs or blocks 1", three of such blocks, arrangedequidistantly at acommon distance from the bolt, being shown in Figs. 3 and 4. The studsor blocks are soldered to the disks. The disks are preferably made ofwire-cloth with fine mesh adapted to intimately subdivide the gas in itsnatural movement upward through the water in the vessel, and such"wire-cloth possesses inherently very little strength; but the bending ofthe disks into' annular flanges at the edges and the provision of thebushings s and studs 1" to space the disks apart give the diskssufficient stiffness and support.

A shoulder t, shown formed by a strap t, is

provided within the shell 0. at the top of the 'series of disks,andserves, when the shell is secured upon the bottom I), to hold thegroup of disks firmly together in the required position. The lowestthree of the disks are each shown with flanges n reflexed around a metalhoop M, which serves to greatly stiifen the edges of the disks andpermits their handling in the process of manufacture and in assemblingthe parts together to form the carbonator, The flanges upon the otherdisks are not only bent downwardly at n, but also inwardly at n upon thebottom edge to form a bearing-surface where each flange rests upon thetop of the disk below. The depths of all the flanges, studs 7, andbushings s are uniform, so that the disks when assembled together areall supported parallel with one another.

When the shell a. is released from the bottom by removing the bolts d,the shell can be raised, leaving the series of disks resting upon thebottom, and the disks can then be readily moved and separated forcleaning independently. The interior of the shell can also be cleanedand also the bottom by unscrewing the jet-pipe m from the nozzle f andlifting the grating 7.: from the bottom, and every part of the interioris thus readily reached for cleansing when required.

The lower grating is may be made of coarser mesh than the disks n andmay therefore be made of perforated sheet or cast metal. On account ofthe fineness of the scale the perforations cannot readily be shown inthe drawing; but to show the difference between the grating and thedisks the disks are represented each with a single solid line and a finedotted line beneath it, while the grating is represented with a singlecoarse dotted line.

All the internal parts of the apparatus are made of or coated withblock-tin, the casing a and bottom I) being lined with block-tin, thebushings s, pipe 171, and studs 0' formed of block-tin, the screens 17.platedwith tin, and the bolt q and all of the parts of the valve 1' andfloat 7' similarly protected.

To form the shoulder within the casing to hold the screens in place, afiat iron strap i, coated with tin, is bent to fit inside the upper partof the casing and formed with elbows 25 upon its ends to contact withthe upper screen. A single bolt 1; in the top of the casing suffices tohold such strap in place. Such means of forming the shoulder is employedto avoid penetrating the block-tin lining of the casing below thewater-line 20. If desired, the bolt can be extended through the gratingand tapped into the bottom Z); but the construction shown permits thescreens n to be separated most readily for cleansing when the casing isremoved.

Operation of the apparatus: The gas introduced through the pipe m isdischarged downwardly to distribute it beneath the bottom screen a,through which it rises and passes upward gradually through the otherscreens, mingling with the layers of water between the several screensand being thus absorbed rapidly by the liquid. When the charge of wateris carbonated, the liquid may be drawn gradually from the pipe g andfresh water supplied through the valve i. The gas in such case continuesto rise through the screens and carbonates the water as it flowsdownwardly toward the outlet. The grating 70 is provided below the pipe91?. to prevent the gas from passing too readily to the outlet-pipe gwhen the carbonated water is being drawn from the apparatus.

Having thus set forth the nature of the invention, what is claimedherein is- 1. In a carbonator, the combination, with the shell a havingwater-inlet at the top, and provided with removable bottom havinggasinlet and water-outlet, of the series of perforated disks a eachhaving its edge flanged and connected to a hoop u. to strengthen thesame, and the central rod and bushings to secure the disks together,substantially as herein set forth.

2. In a carbonator, the combination, with the shell a having water-inletat the top, and provided with removable bottom having gasinlet andwater-outlet, of the series of perforated disks at having the flanges nat the edges to space them apart, a spaced series of studs 9" solderedto each of the disks, and the bolt con necting the disks and having thebushings s fitted between the same, substantially as herein set forth.

3. In a carbonator, the combination, with the shell a having water-inletat the top, and provided with removable bottom having gasinlet andwater-outlet, of the series of perforated disks n flanged at the edgesto space them apart, and the stop t upon the shell ct to contact withthe upper disk and hold the series in place, substantially as herein setforth.

4:. In a carbonator, the combination, with the shell on havingwater-inlet at the top and provided with removable bottom havinggasinlet and water-outlet and having a perforated grating secnred justabove the bottom, of the series of perforated disks 71 having theflanges n at the edges to space them apart, the flange of the bottomdisk resting upon the grating as set forth, and the bolt (1 connectingthe disks and having the bushings s fitted between the same, and the nutfor the bolt sustained above the grating by the flange of the bottomdisk.

5. In a carbonator, the combination, with the shell a having water-inletat the top, of the removable dished bottom having gas-inlet andwater-outlet and provided with the perforated grating 7r, formingchamber Z next above the gas-inlet and water-outlet, and the series ofperforated disks at having the flanges n at the edges to space themapart, with bolt q and bushings 8 connecting the disks, and the flangeof the bottom disk resting upon the grating, as set forth.
